3.1
Measurement standards
The V1x Geophone contains a number of pre-defined measurement
standards. Each of them filters the frequency curve according to the
selected standard. The standard also decides the level range. See
section 4.2.1 for a complete list of the standards that can be selected.
3.2
Measurement Data
Interval and transient data are recorded simultaneously within your
V1x Geophone, and will be stored by your connected Datalogger in
interval files and transient files, respectively. For traceability of the
registered data, all data files have an extensive header where all
necessary meta-data is saved, for example serial number and
calibration date, selected standard, threshold level etc.
3.2.1 Interval data
Interval data is normally
the maximum vibration level
over each time
interval and is sent to the Datalogger which saves it in an
interval file
.
The interval data are filtered according to the selected standard.
Instead of taking the maximum level of the measured values, some
standards calculate RMS value before extracting the maximum.
Attached to the saved data in the interval file, there is information
about overload, invalid data and registration status changes.
